Setup:

  • sky130 volare build: e6f9c8876da77220403014b116761b0b2d79aab4
  • Library Compiler T-2022.03-SP3
  • Milkyway T-2022.03-SP3
  • Synopsys DC T-2022.03-SP3

Issue:

open_pdks implements a hotfix for swapped nwell/pwell and swapped VNB/VPB in 41e2da101560ea1b890dd9f34f6b5adec5016eea and 8f6aff1881e5feae49acb6d5be53c4acc91bb235.

With these changes, generate_lib.sh no longer needs to apply the hotfix for 288. Hotfixes for 183 in generate_lib.py and generate_lib.sh will still be needed.

Actual issue: applying hotfix again undoes hotfix applied by open_pdks.
